2021-04-16 02:28:47 -0500 | marked best answer | [ROS2 foxy] Random speed when using navigation 2 Hello, I have been trying to use the navigation2 stack with a real robot recently. The robot is diff-drive if it matters. My issue is that the robot does not seem to follow the max_vel_x parameter value. I have been testing the robot making it plan in a straight line (no obstacles) and i have reduced the inflation parameter so the robot is always in free space for the test. When I set different values for the parameter, the mesured output velocity on the /cmd_vel topic is totally unrelated to the value and seemingly random:
Here is my parameter file for the controller: Any idea on what could cause this issue ? |

2020-12-01 07:30:24 -0500 | marked best answer | [foxy] Is there any equivalent of matrix transformations for tf2 in ros 2 ? Hello, In Ros1 you could use functions from these imports: where you could transform tf to matrix then multiply them, take the inverse or extract informations from them. I have a code sample that do the following and I would like to know if it is possible to do the same with ros2 and tf 2: I think the tf_matrix_ops and tf.transformations are not available in ros2 (or at least i did not find them) so maybe there is a new way to do this kind of thing ? |
